Module aims

The module builds on Systems and Devices 1 by examining the system software that executes upon a computer system in order that the resources of the system can be shared by multiple programmes and users. One important aspect is how basic security and protection mechanisms are provided by the processor and memory system. The approach is to examine system software in terms of operating systems and how they exploit features of the computer hardware to allow multiple programmes to share the same platform securely. This will also involve aspects of programming time sliced concurrent systems, for example processes. Throughout, the module will consider practical examples based on computer systems used today.

Module learning outcomes

S201

Demonstrate application programming of OS-supported concurrency, communication and I/O. Show how the structure of the OS is supported by computer hardware, with specific reference to the hardware features that extend the basic systems introduced in S&D1.

S202

Use basic resource management mechanisms provided by common OSes, including time and memory.

S203

Demonstrate use of the memory protection mechanisms provided by hardware and OSes, including memory mapped I/O.

S204

Demonstrate use of the information security provided by the OS in terms of file systems.

S205

Demonstrate concurrent programming at the process level and show how it is supported by, and implemented on, the system hardware.

S206

Learn to recognise and avoid issues of deadlock, livelock, and starvation.
